I've often used Maltose from the Chinese supermarket near my work. 500g for $1.99

- it doesn't completely ferment out and gives a hint of syrup / sweetness that I enjoy especially with some florally hops. Currently have a Kiwi hoppy blonde in primary with a tub of the stuff in it.
It really only goes in a blonde or lager international style, wouldn't put it in anything else.
Edit: second thoughts yes it might actually go well in a N. English brown ale like Newky Broon where a bit of sweetness is appropriate
If you look closely it's called "Greek Wall" - probably to avoid being sued by the ute mob. Love it.
